When you try to Install a 64Bit Windows 8.1 on Macbook Late 2007 White through BootCamp you might end up with a Black screen with option to select 1 or 2 to Boot from CD ROM.
But this will stuck in that screen as the Older Macbook doesn’t support fully to install 64Bit of Windows.
There are some articles in web which recommends to press 1 and enter before that prompt screen appears.
It doesn’t work for me. so i loaded with Windows 7 on my Macbook. Windows Looks great on my Macbook now
